While we'd forgive you for thinking Daenerys Targaryen's brother Viserys drowning in, y'know, molten gold would make the top spot, you'd be wrong.

As it turns out, GoT's most expensive death was actually when Maisie Williams' Arya Stark finished off Ser Meryn Trant, a knight of King Robert I Baratheon's Kingsguard and the first person on that list of hers.

Meryn met his end in season 5 when Arya stabbed him in the eyes, the chest and the back before promptly slitting his throat. Ouch.
